Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam alignment signals and data transmission are performed sequentially in separate time slots, then beam alignment accuracy is improved, but data transmission latency increases
Solution Approach 1:
The patent applies dynamics by making the beam alignment signal transmission flexible and adaptable to data transmission needs. The base station dynamically determines whether to transmit beam alignment signals in the same slot as data by evaluating data transmission conditions, allowing the system to switch between sequential and simultaneous transmission modes based on real-time requirements, thus resolving the contradiction between alignment accuracy and transmission latency
Solution Approach 2:
The patent uses preliminary action by performing beam alignment signal transmission before data transmission within the same time slot when conditions permit. This preliminary alignment ensures accurate beam directions are established beforehand, enabling subsequent data transmission to proceed without additional alignment overhead, thereby reducing overall latency while maintaining alignment accuracy
2Loss of time
If multiple beam alignment signals are transmitted in the same time slot as data, then data transmission latency is reduced, but signal interference and reception reliability deteriorate
Solution Approach 1:
The patent applies parameter changes by adjusting transmission parameters such as power allocation, frequency resource allocation, and modulation schemes for beam alignment signals based on data transmission conditions. When data and beam alignment signals share the same slot, parameters are optimized to minimize interference while maintaining reliable reception of both signals, thus resolving the contradiction between reduced latency and maintained reliability
Solution Approach 2:
The patent introduces an intermediary mechanism through the base station's intelligent scheduling and resource allocation system. This intermediary evaluates channel conditions, data priority, and beam alignment requirements to determine optimal transmission strategies, acting as a mediator that balances the competing demands of low latency and high reliability by coordinating resource distribution between data and alignment signals
3Productivity
If carrier aggregation is implemented with multiple component carriers, then system throughput is improved, but device complexity and resource management difficulty increase
Solution Approach 1:
The patent applies universality by designing a unified resource management framework that handles multiple component carriers through a single, integrated scheduling mechanism. The base station uses a common set of beam alignment signal transmission rules and resource allocation principles across all aggregated carriers, allowing the system to manage multiple carriers with a universal approach rather than separate complex management for each carrier, thus maintaining high throughput while controlling complexity
Solution Approach 2:
The patent uses segmentation by dividing the management of aggregated carriers into independent, manageable units. Each component carrier can be individually configured and managed according to its specific requirements while following the overall unified framework. This segmentation allows flexible resource allocation and beam management per carrier without requiring complex inter-carrier coordination, thereby achieving high throughput with manageable complexity
